Real Event Fear

What ERP or other techniques do you use to combat fear of cancelation? Especially curious about those with taboo thoughts, false memory ocd and event ocd based off of real events where the fear of cancellation may actually hold some validity. I once did my own ERP not under a therapist but just on my own I decided to create an anonymous account on Twitter and defend a friend who was receiving online criticism. I knew that this would be semi-controversial so I was expecting backlash and when I recieved troll replies it actually seemed to be a really helpful low-stakes exposure activity. Is this something that others have done? Low stakes online posts etc. that you know will recieve negative responses? I have had severe OCD as a kid as pretty much every subtype under the sun, and as an adult I pretty much have all the types under control except for this real event and false memory and taboo thought OCD. It seems like a different beast since it's somewhat realistic in the camcellation culture today, and it's confusing to address. Ive shut down almost all social accounts and it's keeping me from progressing in a career where I need to have an online presence :/

I look back at various past events in my life where I said or did things that I feel really guilty, disgusted, and ashamed about. I replay them in my head for hours. I feel anxious about crossing paths with people that I've hurt or upset in the past or who perceive me badly, to the point that I will avoid going out in public as much as possible. I go out for work, errands, appointments, and occasionally to eat (even though those all give me a lot of anxiety), but I avoid community events where people might recognize me and I tend to isolate myself. The only people I see regularly are my boyfriend, my parents, and my coworkers. I live in a small community and I'm worried about people confronting me publicly and proving what a bad person I must be.

With real event OCD, I don’t know if any of you feel this way, but do you ever feel that the past event(s) that you ruminate about or constantly obsess about are gonna come up in your future and just absolutely ruin you, that’s how I’ve been feeling for months, it just feels like impending doom, and I hate having to even think that my future would be ruined by what I did as a teenager, and I did some dumb things, that I regret so deeply, I just can’t stop thinking about that.
